Hackaday Podcast Episode 252: X1Plus Hacks Bambu, Scotto Builds A Katana Keyboard, And Bass Puts Out Fire

January 12, 2024 by Kristina Panos 4 Comments

This week, Editor-in-Chief Elliot Williams and Kristina Panos met up to discuss the best hacks of the previous week. It’s CES time once again in Las Vegas, and you know what that means — some wacky technologies like this AI pet door that rejects dead mice.

Then it’s on to What’s That Sound, which Kristina managed to nail for once. Can you get it? Can you figure it out? Can you guess what’s making that sound this week? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt.

But then it’s on to the hacks, beginning with a new keyboard from [Joe Scotto] and an exploration of all you can do with an LED strip, like 1D fireworks and roller coasters without any moving parts. From there, we marvel at the ability of sound waves to extinguish flames, and the tech behind life as a quadriplegic. Finally, we examine not one, but two of Jenny List’s finely-crafted rants, one about web browsers, and the other about the responsible use of new technology.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

Hackaday Podcast Episode 249: Data By Laser And Parachute, Bluetooth Hacks, Google’s Gotta Google

December 22, 2023 by Tom Nardi 6 Comments

‘Twas the podcast before Christmas, and all through the house, the best hacks of the week are dancing around Elliot and Tom’s heads like sugar-plums. Whatever that means.

I’d just like to interject for a moment. What you’re referring to as Christmas is, in fact, Happy/Holidays.

Before settling their brains in for a long winter’s nap, they’ll talk about the open source software podcast that now calls Hackaday home, the latest firmware developments for Google’s Stadia controller, high-definition cat videos from space, and upgrades for the surprisingly old-school battery tech that powers the Toyota Prius.

Out on the lawn, expect a clatter about the the state-of-the-art in DIY camera technology, the acoustic properties of hot chocolate, and a storage media from the 1990s that even Al Williams had never heard of.

Finally, after tearing open the shutters and throwing up the sash, the episode wraps up with a discussion about wiring techniques that let you leave the soldering iron at home, and the newest chapter in the long history of transferring data via parachute. Miniature sleigh and eight tiny reindeer sold separately.

Download the gift you really want this year: this week’s podcast in DRM-free MP3.

A Look At All The Badge Hacks Of Supercon 2023

November 15, 2023 by Tom Nardi 6 Comments

For those of you who’ve had the opportunity to join us in Pasadena for Supercon, you’ll know it’s a wild ride from start to finish. Singling out a single moment as our favorite is pretty much impossible, but certainly the Sunday Badge Hacking Ceremony has to rank up there. It’s the culmination of ~78 hours of intense hardware and software hacking, and that’s not even counting the pre-show work that attendees often put into their creations. Every year, without fail, this community manages to pull off badge hacks that are beyond anything we could have imagined — and we’re the ones who made the thing in the first place.

Unfortunately, in the mad rush, we’ve never had a chance to actually photograph the hacked badges and share them with the Hackaday readers. This year, at the urging of some of the badge hackers themselves, we were able to throw together a suitable overhead light at the last minute and actually snapped shots of each badge after it was presented to the audience.

The resulting images, sorted by badge hacking category, are below. While some proved difficult to photograph, especially with an impromptu setup, we’re happy to at least have a complete record of this year’s creations. Hopefully we’ll be able to improve on our technique for 2024 and beyond. If yours shows up, or if you’d like to share your appreciation, sound off in the comments below!

Hackaday Prize 2023: Green Hacks Finalists

August 4, 2023 by Tom Nardi No comments

Time and tide wait for no hacker, even if they happen to spend their spare time working on the sort of eco-friendly projects that qualified for the Green Hacks challenge of the 2023 Hackaday Prize. This environmentally conscious round ended last month, and after plenty of carbon-neutral debate, our panel of judges have settled on their ten favorite projects.

As a reminder, the following projects will not only receive a $500 cash prize, but will move on to the Finals. They’ll then have until October to put the finishing touches on their creations in an effort to claim one of the final six awards, which includes the Grand Prize of $50,000 and a residency at the Supplyframe DesignLab. Although there can only be ten finalists for each round of the Hackaday Prize, we’d like to thank everyone who put the time and effort into submitting their Green Hacks. We’ve only got one Earth, and we’re all going to have to work together if we want to make sure it stays beautiful for future generations.

Sweet Hacks

July 15, 2023 by Elliot Williams 6 Comments

While talking about a solar powered portable Bluetooth speaker project on the podcast, I realized that I have a new category of favorite hacks: daily-use hacks.

If you read Hackaday long enough, you’ll start to categorize everything. There are the purely technical hacks, beautiful hacks, minimalist hacks, maximalist hacks, and then the straight-up oddball hacks. Sometimes what strikes us is the beauty of the execution. Sometimes it’s clever choice of parts that were designed to do exactly the right thing, and simply watching them do their job well is satisfying, and other times we like to see parts fooled into doing something they have no right to.

While I really like the above speaker build because it’s beautiful, and because it uses a clever choice of audio amplifier to work with the supercapacitors’ wild voltage swings, what really struck me about the project is that [Jamie Matthews] has been using it every day for the last nine months. It’s on his desk and he uses it to listen to music.

That’s a simple feat in a way, but it’s a powerful one. Some of my absolutely favorite projects of my own are similar – they are ones that I use all the time. Not the cliche “life hack”, which are usually like a clever way to peel a grapefruit, but rather hacks that become part of daily life. So look around you, and if you’re anything like me, you’ll find a number of these “daily driver” hacks. And if you do, celebrate them.

(And maybe even send ’em in to the tips line to share!)

Pokemon ROM Hacks Brought To The Real World

February 27, 2023 by Bryan Cockfield 4 Comments

If you were a kid anywhere in the last 30 years, it was nearly impossible to avoid at least some exposure to the Pokemon franchise. Whether that’s through games like Red and Blue to Scarlet and Violet, the brief summer everyone played Pokemon Go, or to other media such as the trading card game or anime, it seems to have transcended generations and cultures fairly thoroughly. And, if you’ve consumed all there is of official Pokemon video gaming, you may be surprised to know there are a number of slightly modified games floating around out there that can be translated onto game carts just like their official counterparts.

[imablisy] has played a lot of these ROM hack games but always within something like a virtual console or emulator, so he wanted something physical which would work on original hardware of the era. For this he’s making physical copies of Flora Sky and Vega, which are based on Pokemon Emerald and Fire Red originally for the Game Boy Advance. To get the cart he found a bunch of Mother 3 cartridges to use as the donor. From there he backed up his Emerald and Fire Red cartridges, modified the ROMs with the modifications, and then sent those new ROMs to overwrite the data on the Mother 3 cartridges.

A playable cartridge is only half of the build, though. He wants these to look and feel like real Pokemon games, so he added a color-appropriate translucent case and also printed custom holographic labels for each. It might seem straightforward, but from the style of [imablisy]’s video it’s clear he is very familiar with processes like these, from the artwork all the way to the hardware and software side. We’re also pleased no classic hardware was damaged during this build, much like this version of Doom on an NES cart which used a common game for the donor to upset the least number of collectors.
